Finite Element Analysis
JBL specializes in finite element analysis using Abaqus. What is Finite Element Analysis (FEA)?
Briefly, it is a way to model physical components using systems of analytical equations and constitutive models
Geometry is created
Geometry for the component(s) is drawn using a computer aided drafting package or with tools available in Abaqus/CAE
|
Geometry is divided into a network of elements and nodes
The geometry is "meshed" or discretized into small volumes and surfaces, creating a network of nodes (points) and elements (areas in 2D; volumes in 3D)
|
Material properties are defined with constitutive models and test data--Abaqus supports many common material models in addition to allowing fully user-defined materials
|
Differential equations can be written as algebraic equations
The governing differential equations describing the physics of the problem are expressed as algebraic approximations within the FEA software package
|
The software's pre-processor develops matrix representations of the algebraic governing and constitutive equations that are iteratively solved for all nodes in the model
|
Displacement, stress, temperature, velocity, etc. fields can be visualized after computations have completed
Once a converged solution is reached (meaning that the matrix equations have been solved within a specified tolerance), a post-processor can be used to visualize the relevant fields within the geometry
